摘　　要：黄河下游因剧烈的游荡特性与悬河特征使其河道治理成为世界性难题,黄河流域生态保护和高质量发展已上升为重大国家战略,其主要目标任务中明确提出要保障黄河长治久安。然而,299 km游荡型河段河势未完全控制,危及大堤安全。根据国家战略对河道治理的新要求,在总结下游游荡型河道整治历程的基础上,分析了新时期下游游荡型河道整治在黄河防洪体系中的地位、作用以及提升治理目标,剖析了目前游荡型河道存在的问题及需要应对的挑战,提出了完善河道整治工程措施、加强畸形散乱河势治理、研发仿生态工程新材料与新坝型等提升治理对策,支撑新时期河道和滩区综合提升治理工程的实施。River regulation in the lower Yellow River has become a worldwide problem due to the characteristics of violent wandering and sus⁃pended river.Ecological protection and high⁃quality development in the Yellow River basin have become a major national strategy and the main objectives and tasks are to ensure the long⁃term stability of the Yellow River.However,the wandering reach river regime of 299 km is not fully controlled,which endangers the safety of the levee.According to the new demand of national strategy for river regulation,on the ba⁃sis of the downstream wandering river regulation course,the status,role and improving the control objectives of the downstream wandering river regulation in the new period in the Yellow River flood control system were analyzed,the current problem and challenge of the wandering channel were dissected and the improving management countermeasures were put forward,such as improving river regulation engineering measures,enhancing the control of deformity messy river regime,research and development bionic engineering new material and the new dam type,which would support the implementation of comprehensive improvement project of river channel and beach area in the new period.
